1. Chapter 1

To the Bishop of Aquileia.

I. Through the negligence of the authorities the Pelagian heresy has been spreading in his province.

From the account of our holy brother and fellow-bishop Septimus which is contained in the subjoined letter, we have understood that certain priests and deacons and clergy of various orders in your province who have been drawn in by the Pelagian or Cælestian heresy, have attained to catholic communion without any recantation of their peculiar error being required of them; and that, whilst the shepherds set to watch were fast asleep, wolves clothed in sheep-skins but without laying aside their bestial minds have entered into the Lord's sheep-fold: and that they make a practice of what is not allowed even to non-offenders by the injunctions of our canons and decrees: to wit that they should leave the churches in which they received or regained their office and carry their uncertainty in all directions, loving to continue wandering and never to remain on the foundations of the Apostles. For without being sifted by any test or bound by any previous confession of faith, they make a great point of their right to the privilege of going to one house after another under cover of their being in communion with the Church, and corrupting the hearts of many through men's ignorance of their false name. And yet I am sure they could not do this, if the rulers of the churches had exercised their rightful diligence in the matter of receiving such, and had not allowed any of them to wander from place to place.

II. He orders a provincial synod to be convened to receive the recantation of the heretics in express terms.

Let them by their public confession condemn the authors of this presumptuous error and renounce all that the universal Church has repudiated in their doctrine: and let them announce by full and open statements, signed by their own hand, that they embrace and entirely approve of all the synodal decrees which the authority of the Apostolic See has ratified to the rooting out of this heresy. Let nothing obscure, nothing ambiguous be found in their words. For we know that their cunning is such that they reckon that the meaning of any particular clause of their execrable doctrine can be defended if they only keep i
